I used to think all power supplies were the same. Then I plugged the 120W linear PSU into my WS161. The difference was audible within seconds—a cleaner, more three-dimensional presentation. The background noise floor dropped to inaudible levels. The aviation-grade connectors inspire confidence.

The WS161 deserves a power supply that matches its performance. This 120W linear PSU is exactly that. The DC 18V output is stable under load, and the 6.5A current capacity means the amplifier never starves for power. The difference in dynamic range is immediately apparent.

I've been using the WS161 for months and loved it, but the stock switching adapter always left a slight high-frequency noise floor. Upgrading to this 120W linear power supply was a revelation. The background became completely black—silence between tracks is now absolute. Dynamics tightened up noticeably.

I was comparing this to other DIY modules. The WS161 at this price is a complete system. You get a full 50W amp, RCA outputs, Bluetooth, and access to 32,000 stations—all on a well-engineered board. I built it into a scrap plywood box with some old speakers. Sounds fantastic.

I live in an apartment with dirty power. The WS161 always had a faint background hiss through my high-sensitivity speakers. This linear PSU completely eliminated it. The CLC filtering with high-end caps works. The sealed toroidal transformer also means zero mechanical hum—the unit is completely silent.

I've been an audiophile for 20 years and know that linear power supplies make a difference. The stock switching adapter was the weak link in my WS161-based system. This upgrade delivers on every promise—darker background, reduced noise floor, better dynamics, and tighter bass.

I was skeptical that a power supply could make an audible difference. I was wrong. After swapping the stock adapter for this linear PSU, the WS161's presentation became more relaxed and natural. High frequencies lost their slight edge. Bass became more articulate. The improvement is subtle but meaningful.

I've tried generic linear power supplies with my WS161, but none had the correct voltage and current combination or the right connectors. This unit is purpose-built. The 18V / 6.5A spec is exactly what the WS161 needs for optimal performance. An essential upgrade for discerning listeners.

I've owned my WS161 for two years and always enjoyed it. But after adding the linear power supply, I realized what I was missing. The stock switching adapter introduces subtle noise that you don't notice until it's gone. This unit delivers dead-silent background, improved dynamics, and a more natural tonal balance.

I have a vintage 1970s receiver and wanted to add internet radio without buying a new amp or speakers. The WS161 connects via RCA—done. Now I can stream thousands of stations through my old speakers. The sound is clean and noise-free. The perfect component for vintage HiFi enthusiasts.

I have three WS161 tuners connected to different amps around the house. They all sync via the same Skytune account, and I can control them individually with their remotes. The RCA outputs feed into my whole-house audio system. This is much cheaper than Sonos and gives me access to thousands of free stations.

I use the WS161 on my desk with a pair of small powered speakers. It saves so much space compared to a full-size receiver. The sound quality is excellent, and the internet radio means I always have music. The display is clear and dimmable for night use. Highly recommended.

I wanted an internet radio for my kitchen but didn't want to run a power cord across the counter. The WS161's RCA output connects to my powered speakers. I charge it overnight and it lasts all day. Sound quality is excellent—much better than my phone or a cheap Bluetooth speaker.

Bought this for my dad, who loves classical music but struggles with apps. The WS161 is straightforward—connect to WiFi, pick a station, done. The display is clear, the remote is easy to use, and the RCA output connects directly to his old stereo. He now listens to BBC Radio 3 and classical stations from Vienna.

I finally cut the cord on FM radio. The WS161 gives me access to stations from around the world. The sound quality is far superior to FM—no static. Connected to my vintage Marantz receiver via RCA. The 9-band EQ allows me to dial in the perfect sound.

I wanted a simple internet radio tuner to connect to my powered speakers. The WS161 fit the bill perfectly. Setup took 5 minutes. The RCA output connects easily. The station search via Skytune is fast. The 99 presets are plenty. It has a headphone jack too for private listening. This is a proper component.

I already have a good amplifier and speakers, so I just needed a pure tuner. The WS161 is perfect. Connected via RCA to my old Denon amp—works like a charm. For the price, you can't beat this. Access to 32,000+ free stations. Exactly what I need.

I bought this unit primarily for the road. Hotel stays and vacations were great—I prefer music over TV. Fixing to buy two more and change out all the house audio. You don't need receivers with all the power this delivers. You do need a little tech savvy to get it running, but once it's there, it's there!

The unit arrived relatively quickly. WiFi setup was a bit finicky with just a few buttons, but it connected and worked as hoped. Adding my own stations was tricky at first, but I used Tunersys.net to find stations by province—discovered 72 stations just in BC. In all, I'm very happy with my purchase!

After about a year of use, the navigation would occasionally freeze. I contacted the seller in China, and they sent the correct replacement part. The radio is now back to excellent condition, and I was so satisfied that I bought another WS161. Great sound quality and responsive support—4 stars.

Order shipped quickly. Setup was mostly easy—though finding stations can be a bit confusing at first. The WS161 has a small footprint but very high-quality sound. I've purchased three units over the years because they provide so much enjoyment. Upgrade tip: Pair the WS161 with TUNERSYS 120W audiophile linear power supply—darker background, lower noise floor, superior dynamic stability.

I bought an internet radio construction kit—the design is great, the quality is great, and delivery was fast. If I had known about the newer model, I would have bought that, but I hope software updates will come for this version as well. Thanks Tunersys!

The radio arrived in 14 days as promised and works great. The only reason I didn't give 5 stars is that the preset buttons (1-9) don't work like traditional presets—you have to navigate through menus to switch between favorites. It's a bit cumbersome, but otherwise, a solid performer. Add the matching 120W linear power supply for an even darker background and lower noise floor.

Good communication, fast delivery. The product matches the description, and quality is good. I am happy and will likely use your service again. 4 stars.

Thanks—good service and easy shipping! Very satisfied. I tried the WS161 with its 120W linear PSU upgrade—the background got even darker and dynamics tightened up noticeably. Highly recommended.

The WS161's WiFi signal can be a bit weak when the unit is far from the router. However, after moving the router a bit closer and adjusting the antenna, the connection became stable. Sound quality and features remain excellent. Overall, a 4-star product.
